I would highly suggest staying away from any type of voip (sip/iax/h323/h248) solution for anything that has to do with modems unless your qos is tight from a to z. It's a good way to go bald real fast lol.... my 2 cents.

At the moment we are running 3Com Total Control 1000's but are running out of spare parts as we have failures. Given that this gear is so old trying to source spare parts is proving to be difficult. We do have access to an Cisco AS5200 but are looking for maybe a SIP based solution that could possibly run on our VM farm? Has anyone heard of anything like that or does it even exist? What kind of gear are you running if you still are supporting dial up customers? Thanks in advance -- Will Duquette GWI Network Systems Engineer www.gwi.net
